Description
Technical field
This utility model relates to medical dressing technical field, specifically comprises a kind of two-layer compound and protects wound dressing.
Background technology
Skin is the natural cover for defense of human body, to maintaining the stable of internal milieu and stoping microorganism invasion to play an important role.Because burn, wound, skin ulcer or other reasons cause large-area skin injury, often there is a large amount of transudate, infection in this kind of wound, even the symptom such as slough and stench.After burning, wound, the final goal for the treatment of is rebuild exactly or recovers skin barrier function, before reaching this target, the Wound dressing of a function admirable temporarily can substitute the partial function of skin, an environment being conducive to wound healing is provided, waits for wound surface epithelization or be transitioned into and rebuild permanent skin barrier.
At present, the dressing kind being used for the treatment of such wound has a lot, and wherein alginate dressing is a kind of functional dressing having high sepage absorbability and hemostasis feature concurrently.The alginic acid calcium salt that it is rich in, after absorbing wound exudate, forms soft hydrogel, has protective effect, accelerating wound healing for wound tissue; Although alginate dressing has good therapeutic effect, the stench abnormal flavour occurred with wound in therapeutic process is difficult to be controlled effectively, and nursery work that is physically and mentally healthy on patient and medical personnel all produces certain impact.
Emerging nano-silver active carbon fibrous material has good deodorization and sterilization effect.Its dressing made effectively can adsorb wound exudate, pins wound abnormal flavour simultaneously, also can promote inflammatory resolution, reduces the formation of secretions.But when processing wound, soft hydrogel can not be formed, but make wound be in a kind of environment of drying, Moist healing environment of comparing, and being unfavorable for wound healing.Above two kinds of dressing all have respective feature, but all cannot meet the needs of clinical Wound treating completely.
Polydatin primary efficacy has expelling wind and removing dampness, expelling phlegm for arresting cough, heat-clearing and toxic substances removing, invigorating blood circulation addiction.Modern pharmacology tests also sufficient proof: Polydatin has expansion blood vessel, shock and improves microcirculation; The effects such as blood fat reducing, antiviral, antiinflammatory, antibacterial, anti peroxidation of lipid.As burn wound's medication, can promote that knot is silly, infection, minimizing wound surface ooze out, prevent moisture and electrolyte from losing, accelerating wound healing, for for the ideal medicine of second degree burn.Therefore, add Polydatin in medical dressing after, both can promote wound healing, antibacterial, and also can desalinate and accelerate wound healing.
Therefore, development one both can be used as temporary dressing for either shallow wound surface, skin donor site, to promote remaining epithelium regeneration, accelerate wound healing, also can be used as one and organize induced material, for deep burn wound, rebuild skin corium, improve the wound dressing of burn of wound healing outward appearance and function, cause increasing attention.
Utility model content
The technical problem that this utility model solves is both to can be used as temporary dressing for either shallow wound surface, skin donor site, to promote remaining epithelium regeneration, accelerates wound healing; Also can be used as one and organize induced material, for deep burn wound, rebuild skin corium, improve the wound dressing of burn of wound healing outward appearance and function.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
